SPECIFICATION forming part of Letters Patent No. 688,124, dated December 3, 1901` Application filed March 29,1901. Serial No. 53,546. (No model.)

T0 all whom it may concern:

Beit known that I, JOHN AINswoR'rH RIcE, a citizen of the United States, and a resident of Bland,in the county of Bernalillo and Territory of New Mexico, have invented a new and Improved Telephone Attachment, of which the following isafull, clear, and exact description.

This invention relates to attachments for telephones; and the object is to provide in connection with a telephone an automatic relay for operating vibrating electric bells remote from the telephone, such as in dierent parts of a machine-shop, Where a loud ordistinct alarm is necessary to call attention to the telephone.

I will describe a telephone attachment embodying my invention and then point ont the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is an inside View of the door of a telephone-box, showing an attachment embodying my invention as applied thereto. Fig. 2 is a similar view, but showing the parts in inactive or normal position. Fig. 3 is a section on the line x of Fig. 2, and Fig. 4 is a diagrammatic view illustrating the electric circuit.

Referring to the drawings, l designates a telephone-box door, on the outer side of which the gongs 2 are mounted and which are sounded by a clapper 3, operated from the magneto in the usual manner. The relay comprises two arms or levers 4 5, mounted to swing on the inner or outer side of the door l. As here shown, these arms or levers are crossed and swing on a pivot 6, which is in electrical con-- nection with the line-wire 7 of a local circuit. The upper ends of these arms or levers embrace the opposite sides of the clapper 3, and the lower ends are turned outward to engage, respectively, with spring-yielding contacts 8 and 9, attached to the ends of a bracket l0, secured tothe inner side of the door, and this bracket 10 is in electrical connection with the wire 11 of the local circuit. I have shown a battery 12 arranged in this local circuit and also a vibrating bell 13. It is to be understood, however, that while I have shown but one vibrating bell a greater number may be Vincluded in the circuit.

In operation when the magneto of the telephone is operated and the electromagnet la is energized the clapper 3 will be vibrated to sound the gongs 2 alternately in the usual manner. This vibrating movement of the clapper will cause a vibrating movement of the arms orlevers of the relay, causing them to alternately make and break contact through the contacts 8 and 9, thus closing the local circuit and sounding an alarm or alarms therein.

The lower ends of the levers or arms4 and 5 being heavier than the upper ends, they will be caused to automatically swing to normal position, or, in other Words, when one arm is operated upon by the clapper the other will follow the clapper to the extent of its movement.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In connection with a telephone, a local circuit containing an alarm or alarms, and a circuit-closer in or outside of the telephoneboX for controlling said circuit, the said circuit-closer being operated by both the back and forth movements of the clapper of the telephone-bell and having normal connection with the local circuit, substantially as specified.

2. In connection with a telephone, a local electric circuit in which an alarm is arranged, a circuit-closer within or outside of the telephone-box and having connection with said local circuit, the said circuit-closer comprising swinging arms having connectionwith the vibrating clapper of the telephone-bell, and contact-fingers coacting with said arms, the said con tact-lin gers also being in the electric circuit, substantially as specified.

3. In connection with a telephone, a local circuit in which an alarm is arranged, a circuit-closer in or out side of the telephone-box and consisting of two arms crossed and mounted to swing independently one of the other, the upper portions of said arms engaging with the clapper ot the telephone-bell, spring contact-fingers adapted to be engaged by the IOO having their upper endsy engaging with the telephone-bell clapper, the lower ends of said arms being turned outward, and contact-fingers adapted to be engaged by said outwardly turned ends, the. arms and contact-fin gers being connected in the local circuit, substantially as specified.

In testimony whereoi: I have signed my name to this specification in the presence of two subscribing Witnesses.

JOHN AINSWORIH RICE.
